WATCH PENDANT AND BOW.

Application filed August 5, 1885. Serial No. 173,647.

To (LZZ whmn it 727/661] concern.-

Be it known that 1, Lotus JOSEPH VILLE- nor, a citizen of the French Republic, residing at Besanr-on, have invented certain new and useful Improvements in Fastening Rings on Watches without Keys, and for other like Purposes, (for which I have received French Letters Patent No. 163,667, dated August 8, 18st,) and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled inthe art to which it appertains, to make and use the same, reference being had to the accompanying drawings, and to the letters or figures of reference marked thereon, which form a part of this specification.

My invention relates to improvements in watches, and relates more especially to improved means for securing the rings of watches to the pendants thereof, whereby said rings are held securely, and thereby preventing displacement of the crowns of said watches. By the means which l employ the ring of a watch may be easily secured in place and removed when necessary from any cause.

I are also very simple, as will be seen from the Lil description hereinafter taken in connection with the drawings.

The invention consists in the combination of parts, as will be fully described hereinafter, and then specifically pointed out in the claims.

In the drawings, Figure l is an elevation of so much of a watchcase and pendant as is necessary to illustrate my invention; Fig. 2, a vertical section thereof; Fig. 3, a detached top plan view of the plate employed for covering the crown of the watclrpendant, and Fig. at a section thereof on line a y.

in the above-described drawings, A indicates a portion of the case of the watch, having the pendant B, the latter terminating at its top in an upright wall or flange, B, forming an annular or elliptical shaped cavity or chamber, for purposes described hereinafter. Through the pendant extends the stem 0 of the watch, the upper squared end of which stein projects into the cavity of the pendant.

Upon the squared end of the stem 0 is mounted. the crown D, which may be of the usual construction. This crown fits within (N'o model.)

These means TCIFICA'IION forming part of Letters Patent E0. 340,467, dated April 20, 1886.

the chamber of the pendant, and is of such diameter as to allow of the turning of the same therein readily for winding or setting the watch.

D represents the ring, which may be of elliptical or annular form. The ring which I have illustrated is of elliptical form, a portion of the same being removed. The ends of this ring terminate in enlargements perforated for the reception of a pin, E, one end of which is headed while the other end is threaded. The flange of the pendant on opposite sides is also perforated.

F is a plate of the form shown in Fig. 3,

this plate being provided with a central hole or perforation, F, extending through the same in cases where a push-pin is made use of. The plate F is also provided with a longitudinal perforation, F for the passage of the pin E therethrough. This plate F, as will be seen, is fitted in the upper portion of the chamber of the pendant above the crown D, and pie vents the latter from becoming displaced from its position on the stem (f.

The manner of securing the various parts together is as follows: The crown D is first placed in position on the stem 0, the plate F inserted in the chamber of the pendant over the crown. The ring D is then placed so that the perforations in the ends thereof, anti in the pendant, and in the perforation F in the plate will all register with each other and form one continuous passage for the pin E. The latter is then inserted and screwed up until the parts are held in a rigid manner, one of the ends of the ring having preferably a countersink for the re ception of the head of the pin, so that the same will be practically hid from view. it will thus be seen that the pin E serves a pivot for the ring D to turn thereon, and when any wear occurs this can be compensated for by simply screwing up the pin E. Although I have shown but one of such pins E, it is obvious that two such pins could be employed. In

this case each end of the ring would be provided with a pin which would extend through the perforation in the end of the ring, through aperforation in thependant, and partlythrough the perforation in the plate F, the perforation in the latter being threaded for the reception of the threaded end of the pin.

1 preferably 5 'When it is necessary from any cause to re move the ring or crown, the pin (or'pins, if more than one is employed,) F is unscrewed and withdrawn, leaving the ring free. The plate E and crown can then be removed, if

10 desired.

I claim 1. In a watch, the combination, with the pendant terminating at its upper end in a chamber, a stem projecting into said chamber 15 and carrying the crown, a plate placed in said chamber over the crown and the ring, of a pin or pins passing through the ring and through the pendant and plate, as described.-

2. In a watch, the combination, with. a

pendant terminating at its upper end in a chamber, a stem projecting into said chamber and squared at that end, a crown mounted thereon, a plate fitted in said chamber over the crown, and the ring, of a pin or pins passing through said ring, pendant, and plate, as described.

3. The combination, in a watch, with the pendant B, stem O,'crown D, and plate E, of the ring D and pin F, constructed and arranged substantially as described.

In testimony that I claim the foregoing I have hereunto set my hand this 1st day of July, 1885;

LOUIS JOSEPH VILLEROT.
